The goals reached in the second quarter of the original contract are the completion of the /sup 1/H NMR analysis of all of the concentrates (monoaromatic, diaromatic, polyaromatic-polar and saturates) and GPC (gel permeation chromatography) fractions 211-76 No. 16 and 24 (diaromatic) and 210-76 No. 16, 21 and 26 (polyaromatic-polar) distillates (535 to 670/sup 0/C) of Wilmington crude and the concentrates and GPC fractions 207-76 No. 15 and 24 (diaromatic) and 208-76 No. 15, 20 and 25 (polyaromatic-polar) of Gach Saran crude. In addition, the /sup 13/C NMR analysis was completed of the monoaromatic GPC fractions of Wilmington (209-76 No. 15 and 23) and Gach Saran (Concentrate and 206-76 No. 14, 18 and 22) distillates as well as the /sup 13/C NMR analysis of the concentrates of the diaromatic, polyaromatic-polar and saturate fractions of Wilmington and Gach Saran distillates. The acquisition of /sup 13/C NMR spectra of the remaining fractions is steadily progressing, although long acquisition times (for example, 63 hours per spectrum) will slow somewhat the rate at which data can be obtained.
